JAMES S. ANDREWS, OF NEW YORK, N. Y.

UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed June 1,1907. Serial 376,854.

To all whom it may concern:

Be it known that 1, James S. ANDREws, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Underframes for Cars,of which the following is a specification.

This invention relates to underframes for railway cars and its objectis, primarily, to provide a metal under-frame of strong and substantialconstruction and composed of standard sections consisting of steelcastings and bars. I

Another object of the invention is to reduce the cost of manufacture,assembling and repairing by making the sections according to acomparatively few patterns and so as to be interchangeable, andassembling them in a manner which will permit the sections to be easilyreplaced. I

In the accompanying drawings illustrating one embodiment of theinvention Figure 1 is a top plan view. Fig. 2 is a bottom plan view.Fig. 3 is a sectional view on the line 33 of Fig. 1. Fig. 4 is anenlarged detail view of the forward end of one draw-bar sill and showingparts of the end sill. Fig, 5 is a sectional view on the line 55 of Fig.4. Fig. 6 is an end view. Fig. 7

is a sectional view on the line 77 of Fig. 1. Fig. 8 is a sectional viewon the line 88 of Fig. 1. Fig. 9 is a detail sectional view on the line9 9 of Fig. 1. Fig. 10

is a detail view showing the joint between two sections of a side sill.

Referring to the drawings the sidesills consist of two end sections 11and a central section 12 (Fig. 1), these sections being made of caststeel in channel form (Figs. 7, 8). The upper flanges 13 of the sectionsof theside sills are depressed at their adjacent ends 14 to receive theupper tie plate 15 and rivets or bolts pass through this tie plate, theflanges 13 and the bottom tie plate 15 to secure the sections together.The lower flanges 13 are also secured together by rivets or boltspassing through said flanges and through tie plates 16, 16 on oppositesides thereof (Fig. 3).

At each end of the frame is a draw-bar sill 17 which is provided with anopening 18 to receive the draw-bar and its attachments. The draw barsill has side projections 19 which abut against side projections 19 onthe projections 19. These projections are provided with suitableopenings 21 for the brake rods and other parts (Fig. 8).

The draw-bar sill has a center bearing 22 on the bottom thereof (Figs.2, 8). The draw-bar sills also have I-shape' projections 23 whichconstitute the end sections of the center sill and are connected attheir inner ends to the ends of the middle I -shape section 24 of thecenter sill. The sections 23 and 24 are secured together in the samemanner as the sections 11 and 12 of the side sills, by rivets or boltspassing through tie plates 25, 25 and the upper flange 26 of saidsections, said upper flange being depressed at the ends 27 so that theupper tie plate 25 will lie flush with the top of the sections of thecenter sill. Tie plates 28 are arranged on the upper and lower sides ofthe lower flange 26 of the sections 23 and 24 and are secured thereto byrivets or bolts (Fig. 3). Each draw-bar is provided at its forward endwith an integral bufling surface 30, an opening 31 for the draw-bar(Fig. 6), and a pocket 32 for the draw-bar carry-iron 33 (Fig. 5). Theend sill is made in two sections 34 and these sections are provided ontheir inner ends with cars 35 which lap over the side flanges 36011 thedraw-bar sill and are riveted or bolted thereto (Figs. 4, 5, 9). The web34 of each end sill section is riveted or bolted to a front flange 36 onthe draw-bar sill (Fig. 5). The outer end of each end sill section hasan car 37 at the top which is riveted or bolted to the upper flange 13of the side sill section 11 and it also has a flange 38 which is rivetedor bolted to the web of the side sill section (Fig. (3).

The transoms 39 are preferably made ofchannel iron and riveted or boltedat their ends to lugs 40 on the side sills and lugs 40 on the centersill (Fig. 7). Diagonal braces 41 are secured to lugs 42 on the sidesills and to lugs 42 on the center sill, and straps 43 connect thesebraces to the transoms above them (Fig. '7).

The underirame consists of comparatively few parts, many of which areduplicates so that they can be made with the same patterns. This enablesmany of the parts to be used interchangeably; for example, the draw-barsills are made alike and are interchangeable and the end section of eachside sill is interchangeable with the end section at the opposite end ofthe other side sill. The sections of the underframe are made so thatthey can be easily secured together in, a strong and rigid manner andany section can be readily removed and repaired or replaced.

What I claim and desire to secure by Letters Patent is:

1. An under-frame for cars comprising a metal side sill provided with anintegral projection constituting a part of the body bolster.

.flanges to overlap the ends oi the projections 2. An tindertrame forcars comprising a metal side sill. said side sill comprising a caststeel section provided with an integral projection constituting a partof the body bolster.
